SharePoint 2010 beta error – Unable to connect to the Synchronization Service

I am trying to connect to the Synchronization Service Manager Client (from C:Program FilesMicrosoft Office Servers14.0Synchronization ServiceUIShellmiisclient.exe) to verify that my user profiles are correctly being synchronized from my AD and I get the following error:

Unable to connect to the Synchronization Service.Some possible reasons are:1) The service is not started.2) Your account is not a member of a required security group.See the Synchronization Service documentation for details.

I am logged in as the service account which is a farm administrator.

Any ideas what is happening? This worked fine before I re-installed SharePoint 2010 on the box.
